I want to implement a complementary filter for IMU data fusion than i can't see how we can get the time delay after each data sampling this time will be used for gyroscope numerical integration (dt), i want to know also if there is a function in MCUXpresso API that could help me.

Thanks for you.

Sincerely.

Dear Amine,

If you only need certain delay between the sampling you could try using a timer to do it. Maybe the FlexTimer examples could help with it.

Also the using the PDB module could be a good option for it.

You can find examples for this two modules in the SDK.

I hope this helps you.

Best Regards,
